Abstract

The invention discloses a small broadband dual polarized quadruple ridged horn antenna. Two pairs of orthogonally arranged exponential modulation sine gradient ridges are respectively inserted into avertical channel of a square reflection cavity after an interval is reserved and are compressed and fixed by virtue of a rectangular gasket, two SMA feed joints provided with a square flange plate aremisplaced up and down and orthogonally fixed at the middle parts of the outsides of two adjacent metal side walls of the square reflection cavity by virtue of set screws, an insulating medium vertically runs through the metal side walls of the square reflection cavity and insulating medium through holes in the exponential modulation sine gradient ridges and extends to the tail ends of gradient edges of the gradient ridges, and a straight inner conductor runs through the interior of the insulating medium and extends into a location hole in the exponential modulation sine gradient ridge at theother side opposite to the straight inner conductor. The antenna disclosed by the invention is mainly used in mobile and satellite communication equipment and even small unmanned aerial vehicle remotesensing monitoring radar equipment, dual polarized broadband earth observation is realized, the overall size is small, a feeding mode is simple, and broadband dual polarization requirement and multi-antenna high integration density use of the antenna can be well met.

Description

technical field [0001] The invention belongs to the technical field of antennas involved in microwave communication, remote sensing monitoring, etc., and in particular relates to a small broadband dual-polarization four-ridge horn antenna. Background technique [0002] For the requirements of spectrum detection and earth observation, in order to improve the detection sensitivity and observation imaging quality, multiple antennas are often required to achieve polarization and effective coverage on the spectrum, which is extremely inconvenient especially in the use of mobile devices and field. In order to overcome this problem and facilitate processing and fabrication, it is particularly important to develop a new broadband small dual-polarized horn antenna design. Contents of the invention [0003] The technical problem solved by the invention is to provide a small broadband dual-polarized four-ridge horn antenna with small overall size and simple feeding method.
